There are a lot of reasons why the small production outfits will choose for the stock music over the big budget composition.
The stock market or the called royalty music is actually a lot cheaper. If ever that you will have limited budget with you and you cannot afford to pay for the fee of the composers and then produce and record the material, then the royalty music is right for you. In the very first place, when you gave already your own composition and you do not hire for the professional, then recording it can be costly unless that you will have your own recording studio and you know more about the sound engineering, then you can get away with the stock music. You can only imagine that amount you are going to spend when producing the music all alone. Compared to that of the purchasing of the tune of the internet, making your own record will mean that you will have a huge spending.
The good thing about stock music is that they are licensed music but they are available for the use of the general public. There are some of the productions that actually find it very hard to pick for the music that they will use for the background since there are hassles that can be encountered when dealing with the certain copyrighted material. The good thing about stock market is that you can use it many times as long as you like without any risks. This will mean that you will not face any lawsuit if ever that the composer will hear that you playing his or her music in the radio without any permission from the owner.
Finally, it will also be fulfilling if you have the chance to make use of the material you want. In using the royalty-free makes it no difference after all as you will still get to choose. There can be websites that offers this kind of service where you can use the materials for free. They can provide you with the wide variety of the music you can choose from under some categories. If you are a fan of the certain genre that you feel can be suited best for your production, then you can free to pick whatever will catch your ears and this at very low price only that you can afford.
